Improvement in plaster-sowers



:CHARLES cLADDiNeor IMPROVEMENT IN To all wltontit may 'concern i Be it known that I, CHARLES E. GLADDING, of Towand'a, in the county of Bradford and State of `jlennsylvania, have invented a new and useful `Improvementin Plaster-Swer; and I do hereby declare Vthat the following is a full, clear, and exact description thereof, which willeuableothers skilled in thc art to malte` and use the'same,.reference being had to ,the accompanying drawing forming part of this specification,` in which-' H i Y 1 Figurel is atop "view` of my'improve'd plastersower. t lFigure `2 is a detail vertical section of the same l `taken through the line :c x, fig. l.` j

` Similar letters ,of reference indicate corresponding parts. Myinvention has for itsobject to furnish an improved machine for sowing plaster, which` shall be i simple `in construction, effective, reliable, and uniforni` in operatiemand easily adjusted to sow more or less to the acre, as may be desired 'g and `the various p'arts by means of which the plaster' is distributed or sown. 4

` i A arethe wheels, wbichVevolvehpon the journals of the axle v13 in the ordinarymanucr.

(L` are' the` hafts, which are securely and rigidly attached to the axle B.. y

. "D is the hopper orjplastenreceiver, which is sel curelyattached to the rear side of the axle B.

`The hopper D ismade Vl-shaped/ in* its cross-sec i, tion, and with vertical ends. p

y The forwardhside of the hopper is secured to the `below the lower-edge of the rear side, to serve as a guard to prevent the discharge orifice from beingwet by the grass or grain and becomingv clogged with wet f plaster. y j' The lower edge of the rear side of the hopper does not come quite down to the rear surface ot' the for- .iward side o'fsaid hopper, aspace being left vfor the escape of the plaster. i

"rear and `front sides of the hopper is regulated by the plate E, which ,extends along the inner or for- `wardsurface of the rear side of the hopper D, and has l-ods or arms formed upon its ends which pass screw-threads cut upon their outer `or projecting ends to receive the nut-s" e', by means of which the' said plateis clamped in place when adjusted. j

"The plate llispivoted to the lower ends of two or more "arms lf, the upper Vends `of which extend `up "aleng and are pivoted to therear side-board otn the hopper, soas to keep the plate E horizontal as it is moved up or down. i

y The Schedine referredto in these Letters Patent and soaking partici the same.

i It consists in the construction and combination of axle B, and'the lowen edge ofl said side projects throughylslots in4 tbe-.ends of' said hopper, and have roWANDA, PENNSYLVANIA.

By this construction, by loosening one ot' the nuts .c and tightening the other, the plate E will be raised to enlarge the discharge-opening, and by .reversing the operation the said plateA will be loweredto diminish saiddischarge-opening.

tend nearly to the discharge-opening in the bottom of'said hopper, and are bent outward, as shown in figs'. lrgaud plate E.

The bars G are connected, held in their proper relative positions, and made to move together, by the bar H, which extends longitudinally along the inner `surface of the lower part of the forward side of the hopper, and to which the said bars Gr are pivoted.

I are bars, which are pivoted tothe bars H by the. same rivets or pivots that pivot the bars G- to said bai-SH.

`The bars I are pivotedjto the inner surface of. the forward sideof the hopperD, and their lower ends project through the discharge-opening in the bottom of the hopper.

The upper end of one of the bars G is extended upward` above thefupper Aedge of the hopper, and to its projecting end is pivoted the cou'nectingfrod J, the outer part ot' which passes through and is pivoted to an nprght,`K, the lowerend of which is pivoted to the axle B.

to receive the rim of the cam-wheel L, which is attached to one of the wheels A, so that as the machine is drawn forward the revolution of the cam-wheel L, may operate the bars G and I to insure the continuous aud uniform discharge of the plaster.

Having thus described niy-invention,

y I. claim as new and desire to secure by Letters Patent-1 1. rlhe combination of the`pivote`d bars Geconnectng-bar H, pivoted bars I, connecting-rod J,

` pivoted support K, and cam-wheel L with each other Thelsize of the discharge-opening between the.

and with the drive-wheel A, axleB, and hopper D, substantially as herein shown and the purpose set forth.

2. The combination of the adjustable plate E', clampving-nuts pand pivoted arms F with the discharge# opening in the bottoni ofthe hopper D,- when usedin connection with the pivoted arms or barsG and I, substantially as herein shown and described, and for the purpose set forth.

W. T. DAVIS, C. L. LAMB.

Tothe upper' part ot' the inner surface of the forl ward side of the hopper D are pivoted the upper ends," of a number of bars, G, the lower ,endsl of which exv 2so as to point toward the adjustable j Upon the outer end of the rod J are .formed jaws described, aud for v CHARLES E. GLADDING.
